This invention 'relates to smoking pipes fand relates vmore particularlyto va novel pipe where- "in the yuser Imay enjoy a freedrawingtcondition at all times.

An important-object of rtheinventumis to provide animprovede-pipewherein thebowl is formed in two sections which :arePcompletely ydetachable rfrom each other to -correctanysituation tendingto interfere with this free-drawing action.

The-smoking pipe of the present invention is to .be distinguished `fromv.pipes wherein the bowl --is supported in a socket and vis removabletherefrom for the purpose Lof cleaning. In such pipes fthe bowl ,sectionhas -one .or a vnumber .of .small fopenngsin ,the lower wall, formingsmekepassages. After :a period of use, these openings become clogged andcan only be cleaned with considerable difculty. Moreover, if `one:starts to smoke and nds the openings clogged he ,can .clean the pipeonly 'by removing all the tobacco .and starting fresh.

In accordance with vthe-present invention the upper section of the bowlis formed with a ycon- .tinuous bore from top to bottom, 4the borepreferably being uniformly tapered .and having its larger diameter atits upper yend. This :upper section is supported `in interlockedrelation von the lower bowl :section which has ,a vertical openingyleading to a bore through the stein section. When mounted as aforesaid,the bowl may be lled in the usual manner andthe upper bowl section Athendetached romthe lower section `for the pur-pose of removing anyA`tobaccoparticles in the vertical opening.

Alternatively, the pipe may be loaded while inv detached relation, theuser placing a nger over the lower end of the bore to prevent tobaccofrom falling through. He then mounts the upper lled section of the ybowlon the lower section and proceeds to smoke while enjoying a free passageof the smoke through the lower end of this upper section. Should heexperience a clogging action. the upper section is removed withoutdisturbing the tobacco, the obstruction removed from the opening in thelower bowl section, and the parts replaced.

It will thus be apparent that a further object of the present inventionis to provide a twosection bowl wherein the only place any obstructioncan occur is in the lower bowl section which is readily accessible.

'The several forms of the invention Adiffer mainly Vintheparticularmeans -for attachment of the upper bowl section to vthe lower. inasmuch'as a lsmoker who desi-res to .enjoy a completely free draw might removethe upper V'section a number nof :times during his smoke, it is`preerable to employ some quick-'acting joining means such as la bayonettype -o joint oran |interrupted thread, a-l-thoughfan ordinary screw-thread may be used.

The rst formef Athe invention shown in Figs. '1 to 5 eiiects lockingaction by about Ia quarter turnfof -one part 'relative to the-other. Theupper 'bowl section I0 is ofthe usual external contour and is formedwith a vertical, tapered 'bore II. :Sorne'taper is preferable to aboreof `uniform A'diameter since the taper hel-ps to retain all the to-'bacco inthe lupper bowl section. The degree fof taper is a matter ofchoice, the important consideration being that `the Vbore besubstantially uninterrupted, ye. g., characterized by the absence of Vaperforated lower wall.

At `its lower end lthe upper bowl section is formed with a seat -I'-2vand extending ibelow such s'eatr-there is fformed yan annularprojection or male portion I3 whose contour is generally oval orelliptically shaped and whose side walls are undercut. The lower bowlsection I4 is formed with an annular seat I5 of the same externaldiameter and contour as seat I2 and which receives the latterface-to-face contact to prevent leakage.

The upper wall of the lower bowl section is provided with an ellipticalopening or female portion I6 shaped and proportioned as to size as toreceive the male portion I3, the walls of such portions being inclinedas shown to secure the desired dove-tailed or interlocking relation.Thus when the male portion is inserted in the female portion and given apartial rotation the upper section is locked to the lower section. Aninternal annular seat I'I is provided at the lower end of female portionI6 which receives the lower surface I8 of the upper projection I3.

A tapered opening I9 leads downwardly from seat Il', the upper endthereof being preferably of the same diameter as the diameter of thelower end of bore II with which it is aligned 3 when the parts arejoined. The lower end of bore I9 communicates with a horizontal smokepassage 20 in stem section 2|.

The removable mouthpiece 22 is carried by the stem section, theparticular joining means forming no part of the present invention.

In use, it is preferred to rst remove the upper bowl section from thelower, place ones linger over the lower end of tapered bore Il 'and thenfill the bore with tobacco, 1compressing the mass as much as desired,and leaving no part of the mass extending below the lower end of thebore. The upper bowl section is now mounted on'the lower bowl sectionand the user lights the pipe and proceeds to smoke in the usual fashion.

If any obstruction is experienced in the smoke.

passage, the upper bowl section is removed, the obstruction cleared fromthe lower bowl'section as by Iblowing out the offending particle, thetobacco in the lower end of bore Il slightly compressed upwardly, andthe parts re-assembled. 'Any tarry residues in the lower end of the boreor in openings i9-20 can be readily removed, and the pipe alwaysretained in prime smoking condition.

In the modified form of the invention shown in Fig. 6 the constructionis largely the same as in the first embodiment except that in order tosecure a more positive seal between the bowl sections, each of meetingsurfaces l2 and I5 of the upper and lower bowl sections, respectively,are formed with annular recesses 2 and' 25 and a metal or plastic ring26 is secured, as by means of cementing, in one of such recesses,preferably the lower one. Thus, when the bowl sections are assembled amore nearly air-tight seal is effected.

In the second modied form shown in Fig. 7 the upper section 21 has abore 28 of substantially uniform diameter throughout its length and thelower section 29 has a tapered opening 30 whose upper end'is ofsubstantially the same diameter as the lower end of bore 28 and whichleads to the smoke passage 3l in the stem section 32.

In this instance, the meeting surface 33 and 34 of the upper and lowerbowl sections, respectively, are ground flat and are formed with annularrecesses 35 and 36 which receive ringshaped magnets 37 and 38 althoughonly one of the rings may be magnetized. When assembling the bowlsections, the upper section may be lmoved across surface 34 with awiping action to remove any particles on the meeting surfaces.

While three forms or embodiments of the in- ,out departing from theprinciples thereof.

What I claim is: A smoking pipe including a bowl formed in twosuperimposed sections provided with meeting 'surfaces and a stem portionleading generally horizontallyfrom the lower section, such stem portionhaving a smoke passage therein, the upper section having a tapered boreextending from its upper to its lower end and being of smaller diameterat its lower end, the upper surface of the lower section having atapered bore leading into the smoke passage, the upper end of said borebeing of substantially the same size as, and being axially aligned with,the lower end of the upper section bore when the upper section ismounted on the lower section, and means for releasably securing themeeting surfaces of the bowl sections together, such means comprising agenerally oval-shaped male portion of dovetailed cross-sectional contourextending outwardly from one of the surfaces, the other surface having arecess shaped complemental to and which receives the male portion ininterlocked relation upon a partial rotation of the parts.
